> Project: Apache IoTDB

>
> In cluster mode, if we need to create udf without specifying uri, we need to
> make sure that each datanode has the jar in ext/udf, if not so, currently, we
> will throw exception like following:
> !image-2023-11-08-15-21-24-751.png!
>
> To be more user-friendly, we need to make the error msg more readable and
> tell users which datanodes miss the udf jar.
